Method to Pair multiple Bluetooth devices simultaneously through Bluetooth Out-of-band protocol

摘要

The present invention will take the Bluetooth out-of-band information from a mobile device such as a phone, and pair multiple Bluetooth controllers within the vehicle in a single session avoiding the customer from having to manually pair the phone to two different systems. This proposal avoids having to bootstrap the controllers, both can be paired at the same time The steps to perform this simultaneous device pairing out-of-band are as follows below referring to Figure 1: OOB Pairing. 1. Multi-pair controllers communicate with each other to generate a unique identifier that cannot be copied. The two controllers then advertise the ID and that they support the multi-pair feature. 2. The user is informed that there are devices that support multi-pair and when you pair one you will pair them both. 3. User initiates the multi-pairing feature 4. The OOB information is fetched from the controller on the initiating device. This is step 1 of SIMPLE PAIRING MESSAGE SEQUENCE CHARTS of Bluetooth core specification Volume 2 part F section 4.2 x 5. This is step 2 of SIMPLE PAIRING MESSAGE SEQUENCE CHARTS of Bluetooth core specification Volume 2 part F section 4.2 x 6. This is step 4 of SIMPLE PAIRING MESSAGE SEQUENCE CHARTS of Bluetooth core specification Volume 2 part F section 4.2 x 7. This is step 3.b of SIMPLE PAIRING MESSAGE SEQUENCE CHARTS of Bluetooth core specification Volume 2 part F section 4.2 x 8. The OOB data is then broadcasted to the different devices over the internal OOB channel 9. This is step 4 of SIMPLE PAIRING MESSAGE SEQUENCE CHARTS of Bluetooth core specification Volume 2 part F section 4.2 x 10. This is step 5-11 of SIMPLE PAIRING MESSAGE SEQUENCE CHARTS of Bluetooth core specification Volume 2 part F section 4.2 x 11. Same as previous. 12. Start simple pairing again, This is step 4 of SIMPLE PAIRING MESSAGE SEQUENCE CHARTS of Bluetooth core specification Volume 2 part F section 4.2 x 13. This is step 5-11 of SIMPLE PAIRING MESSAGE SEQUENCE CHARTS of Bluetooth core specification Volume 2 part F section 4.2 x 14. Same as previous.
